Hello all,

I am trying to convert the Brainnetome surface atlas which is in a 164k mesh and Gifti format to the 36k niml.dset format common to AFNI. I am new to surface analyses and find the multiple file formats confusing. My initial attempt was to use SurfToSurf, but this output a 1D file without node ROI value and a niml.M2M file which I wasn't expecting.

Could you please advise on this overall pipeline from gifti to niml.dset while also changing the mesh density? Are these two separate transformation or can they be done simultaneously?

Best,

Andrew
